Today I upgraded my Ubuntu distro from 16.04 to 17.04. Result: the keyboard and the usb ports don't work anymore.
I upgraded the distro via command line:
sudo apt update && sudo apt dist-upgrade sudo do-release-upgrade
It seems that I need to install a generic linux kernel.
Problem: if I run the installed version of Ubuntu I cannot install the kernel.
Can I install a kernel on my system from a live session?
